Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for model-shopping. I use this for every prototype before committing.
